Default QUESTION:"Can i make a stereo gainclone with just one lm3886?"

Hi guys, newbie here! haha

So, my question is in the title:"Can i make a stereo gainclone using only one LM3886?".
I saw on the datasheet and it says "compact stereo", what this means?

And if is possible to make, how can i?

I'm just beginning on this eletronic/audio thing, so i really don't know anything haha.

Anyway, thanks!

(*Sorry for bad english, not native speaker!*)

Your English is fine

You need two of the LM3886 chips for stereo. The data sheet wording means its a device suitable to use in 'compact' or 'component' systems.

tries to look on the website of National, a few years ago they sent free books for technical data and also chips. I live in Buenos Aires Argentina and received many.
I do not know if they still continue to do so.

I tried, but on the TI website. They can send some chips, but the LM3886 is out of stock haha.

It seems TI does not provide samples of the older chips. I've received several samples of the LME-series and newer OPA-series products.

When National offered "Samples" the 3886 was excluded.
They charged for sending out the 3886. I paid that charge willingly because it guaranteed genuine product that had passed all tests.

I guess National had to introduce the 3886 charge because so many DIYers were requesting samples for free and it became too big a drain on their advertising budget.

I don't know what Ti's policy is for samples and whether any particularly popular chips are excluded due to misuse by DIYers.
